The SMP31A Series are fully compensated high performance die in a plastic surface mount package. They are absolute pressure sensors fabricated by bonding a micromachined silicon diaphragm to Pyrex glass in a vacuum. Uniform span and offset distribution results from precise implant and etching control. The result is long-term offset stability that is suitable for barometric pressure measurement.
The output is compensated via onboard signal conditioning using the latest ASIC technology. The small package makes this model an ideal product for customers looking for compensated absolute pressure measurement in the smallest possible surface mount package. An uncompensated version of this model, the SMP31 is also available.
